IPC: A61B5/083
Filed: 2017-11-10
Abstract: Resuscitation and ventilation monitoring devices are provided. A device includes an inlet in fluid communication with airflows exchanged with lungs of a patient and an airflow meter for measuring characteristics of the airflows. A user may provide a controller with patient information, e.g., height, weight, gender, or age, via a measurement selector, enabling the controller to determine acceptable ranges of measured airflow characteristics. The device may determine a current mode of ventilation and associated ventilator settings based on the measured airflow characteristics. The device may also identify and filter out artifacts present in the ventilation signal, and determine whether a respiratory failure phenotype is present in the ventilation. If the current mode of ventilation and associated ventilator settings fall outside an acceptable range, the ventilation is classified as off-target and the controller may cause a sensory alarm to alert the user. The device may suggest a corrective action based on the type of off-target ventilation detected. The device may also continuously analyze ventilation to determine changes in lung compliance over time and to identify pathological changes over time. The device may work within a network of devices and user interfaces via wired or wireless communication, and is not restricted to or dependent on the type of ventilatory device with which a patient is being supported.

Abstract: A communication channel for conveying quasi-static signals representing several alternative states one of which is potentially unsafe, e.g. the control signal for a signal lamp in a railway control system. Each channel has a signature code (Figs. 1 and 2) which is continuously repeated in different forms, e.g. non-inverted (Fig. 2(a)), inverted, or alternately inverted and non-inverted (Fig. 2(b)), to represent different states. When a potentially unsafe state is indicated, the repeated signature is periodically corrupted according to a predetermined error pattern. The channel receiver (Fig. 4) is arranged such that its output (32,34) can only be held in the unsafe state providing both the signature and the error pattern in the received signal are correct.

Abstract: A lateral transistor structure having a self-aligned base and base contact is provided, together with a method for fabricating such a structure in which the base width is controlled by lateral diffusion of an impurity through a polycrystalline silicon layer. The resulting zone of impurity changes the etching characteristics of the layer and permits use of a selective etchant to remove all of the layer except the doped portion. The doped portion may then be used as a mask to define the base electrical contact, which in turn is used to provide a self-aligned base for the transistor. Dopants introduced on opposite sides of the base electrical contact create the emitter and collector.
